I'm wondering if we're too late for one more API to round out the API we
added in this release.  Qemu is proposing a new monitor command
system_wakeup which lets the host inject a power-button wakeup to a
guest that has gone into S3 sleep.  Since we added the
virDomainPMSuspendForDuration command to put the guest into S3 from the
host, I think we need a counterpart API that wakes the guest back up,
rather than relying on mouse clicks, serial input, or timeouts doing the
job for us.  It's a shame that virDomainResume() has no flags argument,
and that it is already tied to virDomainSuspend() (aka guest pause), so
I'm thinking something like:

/* Inject a wakeup into the guest that previously used
 * virDomainPMSuspendForDuration, rather than waiting for the
 * previously requested duration (if any) to elapse. */
int virDomainPMWakeup(virDomainPtr dom, unsigned int flags);
